1 To all whom it may concern:

Be it known that I, EDWIN J OHN SIBLEY, a citizen of Canada, and resident of Woodhaven, in the county of Queens and State of New York, have invented certain new and useful Improvements in Friction Adjusters for Screened Windows, of-which the follow in Y is a SIYClfiCfitlOIl.

afhis invention relates to friction casement window adjusters. More particularly the invention relates to a friction type adjuster adapted to be operated through the frame of a WiIldOW screen "for a casement window.

In the South and in other places, local regulations often prohibit of use of casement window adjusters unless they can be operated without opening the screen,which is inside the window.

Several attempts have been made to provide casement window adjusters to be used in connection with screened casement-windows, but inso far as I know, none of these have been successful and very few are in use due to unsightly complicated construction and design, absence of frietion.adjust-' merit and for other reasons.

llhe object of this invention is to provide a fr'etion casement Window adjuster adapt ed to be mounted inconspicuously between the easement window and the screen and so arranged that it may be operated from Within the screen and without necessitating the opening or lifting of the screen in order to open the easement window. In addition,

, it is an object of the invention to provide an adjuster for this purpose provided with self-adjusting friction means for holding the easement Window firmly in any desired *position. A still further object or" the invention is to so arrange the device that it may be quickly attached to the window and window sill and only requires a small cutout in the screen iraiiie in order to be properly secured.

With. the foregoing and further objects inview; which will be pointed out hereinafter, my invention is embodied in a friction type casement adjuster for screened windows arranged and constructedashereinatter set forth and as illustrated in the ac companying drawings, in which Fig. 1 is a plan view of the ad uster mounted in position between the easement window and the window screen, parts being shown in section and parts omitted;

2 is a view in elevation of the parts showwin Fi 1 looking in the direction of juster shown in Figure 5 with parts omitted;

.Fig. '7 is a sectional detail view of the means for releasing the locking device shown in Figs. 1 and 5;

, Fig. 8 is a sectional view taken on. line 8----8 of Fig. i; and

Fig. 9 is a view looking in the direction of arrow 9 in Fig. 7.

Referring to Figs. 1 to t, the reference numeral 10. tenet/es the window frame, 11 represents a casement window pivoted to the frame at 12 and 13 denotes the window screen which is conveniently shown mounted againstthe cleats or frame pieces l i, it. All the foregoing parts are shown eonventionally and may be of any desired con struction and arrangement. The friction casement adjuster comprises a tube or barrel 15, which, in the present instant, is shown as being; of rectangular cross section but which may have any other desirable form. The barrel is pivoted at 16 to a suitable bracket 17 secured to the window as by screws or other means 18. Within the barrel sl des an arm 19st the same cross sec tional formation as the barrel 15. The arm 19 is pivoted on a stud. 2i) and is provided with a handle portion 521. As'seen. best in Fig. it the stud 20 carries at its base a trio tion dsk 22 integral with the stud. The numeral 23 denotes a fixed base plate forming a recess 24 within which are disposed suitable friction members 25, 26, preferably in the form of disks oi different metals or" other suitable material. The arm 19-has a square opening: 28 which fits around the square portion 29 of the stud. A. casing or cover 30 through which the arm 19 passes serves as a means for covering the connection between the arm and the stud and the friction elements. Friction is obtained between the base disk 22 of the stud and the fixed base plate 23 by means oi. the nut Bi side wall and the base 23, which latter is con venientiy secured to the Windowsill 33 by means of screws 84. The base plate forms to one side an upstanding locking projee tion-or in 35. The adjuster handle 21 carries a spring 36 which is provided with a button 37 which projects freely upwardly tion s own in Figs. 1 and 2, the spring 36 is normeily in the path of the said upstanding lug 355 v the arrangement being such that when'the window is closed as in Figrl'the 5 ring 36 snaps in behind the lug and t us prevents accidental-openingof the window and operation of the edjuster. When it is desired to open the window the operator takes hold of the handle-21 and with the fore finger depresses the button 37 below the plane of the lug 35 as shown in dotted l nes as shown in Fig. 3, after which the handle is swung to the left in Fig.1, when-of course, the window is opened as shown in dotted lines. j

Attention is called to the feet end as clearly seen. in Fig. '2, that only a com erstiye :ly smell out-out is required in t e screen 'i'reme 13 in order to mount the odfi'uster in proper posit-ion end this cut-cot is empiissized h the heavy line -39 in Fig. 2. From the ongoing it is clear that the ad juster is inconspicuously mounted directly under the screen frame and on topor the window sill ondthet from the inside of the window only the handle and the casing 30 is seen while the other ports of the, adjuster are hid behind the screen ironic and the windowmey be opened without opening the til? screen and will. remain open in any desired positi'onheceuse of the friction element referred to, and which latter may be adjusted from time to time if desired by operating the nut 31 on the stud 20.

' ite'ferringnow to themodifications illustreted in li gs. '5- to'9, sit the corresponding and similar elements in use with those de scribed shove are similarly numbered. The modificetion consists in e diii erent form of handie' which when operated automatically releases the locking spring end perinits op cre tion oitheiedjnster. I

in detail it will be seen "thee the hendie fidie'in vertical depending osition ss'shown' f r-un in hig 5 end 7. A on the lnnidle is -as shown. throu 11 said handle, and when 1n the'goosi-f 'l he spring 4:) is secure portion to of-the srin 19in Fi 5 is pro messes retracted position as shown in Fi 7 by o coiled spring 59. As a matter o' conven ienL construction, the hendleo'por-tion 40 of the arm 19 is suitably secured within the sleeve 41 and forms a stop for the spring'49 The handle ortiou 4:0 is cut out at 50 to form a recess or the reception of the pin 47 and the bottom of said recess is open as at 51 to permit the finger 48 to progcct upward-1y into the nth or the pin 47. d in any convenient manner below the portion 40 and within the sleeve 41.

It will be seentherefore; that with respect to the friction element the adjuster illustrated in Fig. '5 operates exactly like the adjuster illustrated in Fig" i but that upon raising the hendle 4:3 the looking spring is automatically depressed below the plane oi the log 35 thus permitting operation of the adjuster.- r

The foregoing-is thought toeleeriy describe and illustrate sly-invention. which not alone consists. in improvements in the ed juster es such,-but the invention --includes and consists in the combination between the peculiar form of adjuster shown and the ar rengerncnt with the casement window and the screen therefor whereby" the window may be opened without opening or menipu' io'iing the screen in any manner whstsoever and s t the some time providing a friction type of adjuster for this purpose, which may he used with windows and screens of standard or usual construction, it being on important mature of this invention their my ad uster may be used, with standard case-f ment windows and screens without reuirmg any change In the construction oi ese ports. No false wood work to hide ports.

of the adjuster or change in the window construction or oppearance is required. And in new constructions no specie-l attention is needed toconform the windows or screens or frames or sills for the nrpose n a n 0 a oi. installing my eo uster, which men-ides as on imports-int. element the friction device for holding the window in all positions. Another :teetureot the invention he noted, namely, that operation of the sd= meter-through the window screen home without manipulating the'latter is possible foni because eiiof the-swinging movement of t 1e edju'ster takes place on one side of seid frame jbetween it theopereting art of the adjuster is on the opposite (insi e) side of the screen frame.

in other words it is e%entiei for successful v end the window) while operation and commercialization of the invention that the pivotal ointaround which the adjuster moves lies 1n the plane of the window screen, with the window operating parts on one side of said pivot and the handle part on the opposite side.

.Whereas I have described my invention by reference to specific forms thereof, it will be understood that many changes and modilications may be made without departing from the spirit of the invention, as defined by the appended claims.
